NOZZLE.

Specification of' Letters Patent.

Patented Jan. 14, ieos.

Application filed April 19.1905. Serial No. 256.364.

To all lwhom et 'may concern:

Beit known that I, ERNEST GERLACH, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Nozzles, of which the following is a specication The invention relates to an improvement in nozzles, particularly designed for use in cleansing and flushing the large intestine.

The main object of the invention is the production of a tube of this character so constructed as to be readily inserted to the desired length, and adapted to so direct the fluid ejectedtherefrom as to reach all parts of the organ.

The preferred details of the structure will be described in the following specification, being particularly illustrated in the accompanying drawings, in which:

Figure 1 is a view in elevation of the operative end of the tube of my invention. Fig. 2 is a vertical longitudinal section of the same. Fig. 3 is a side elevation of the nozzle of the tube.

'It has been found highly desirable in a tube of this character to construct and arrange the parts to adapt it for ready insertion, and to provide a discharge nozzle which may be connected with the tube proper and formed to direct the outgoing s ray practically in all directions for proper ushing and cleansing.

To the end above noted my improved tube comprises a tube proper 1, which is preferably of yielding material of sufficient rigidity to permit convenient introduction thereof into the organ, and a nozzle 2 connected to the free end of the tube. The nozzle comprises a head 3, a body 4, and a ni ple 5, the head having a rounded closed disiarge end 6, preferably formed with a series of openings 7, arranged to direct the outgoing liquid in a series of fine streams at varying angles to the plane of the head. Thehead inclines or narrows rearwardly and is connected directly to the body 4, the adjacent end of which body is of less sectional dimension than the rear end of the head to provide a shoulder 8, at the juncture of the head and body. The body is of barrel shape, that is of' great dimension at its central portion and may be of any desired length, being terminally connected to the nipple 5, the adjacent end of which is of slightly greater sectional dimension than the barrel to provide a shoulder 9 at the juncture of the barrel and nipple.

1n the construction described it will be noted that my improved nozzle comprises'a head rounded and practically closed at its discharge end and of gradually decreasing sectional dimension rearward from .said discharge end, being connected at its rear end to the forward end of the barrel shaped body, so as to provide an offset or shoulder immediately in rear of the head.

By preference the nozzle is formed of a single integral structure, and is arranged to be inserted in the open end of the tube l, the edge 10 of said open end being brought into contact with the offset or shoulder 8 of the nozzle. The shoulder 8 is of a depth a proximately equal to the thickness of t e tube wall, whereby when the said tube is in place on the nozzle a Smooth unbroken surface is presented'whereby to avoid obstruction in theintroduction of the device. The convexity of the body 4i, in conjunction with the shoulder 9 tend to effectively prevent accidental separation of the tube and nozzle when connected. l

The introduction of my improved tube is materially facilitated by the enlarged head portion 3 of the nozzle, which is rounded and practically closed at its forward end, and by the fact that the tube is so connected tothe nozzle as to avoid external projection.

By the arrangement of the openings 7 in the head of the nozzle, the outgoing liquidis effectively directed at various inclinations with respect to the plane of the nozzle, and the walls of the intestine may be effectively cleansed and iiushed.

Having thus described my invention, what Iclaim as new, and desire to secureby Letters Patent, is:

A nozzle for colon tubes integrally formed and comprising a head, la tube, and a body portion, the head being of greatest diameter at the relatively forward or free end, with the wallof the head converging from said `free end toward the rear, the body portion being of approximately barrel sha e, the diameter of the head being greater tiian the greatest diameter of the body and applied flexible tube, the tube of the nozzle being of cylindrical form and converging toward the rear or free end, the body portion being arf ranged between the tube and head and being of materially less diameter at its juncture with, these parts than the proximate portion of the respective head and tube, whereby op- In testimonywhereof, I afiii rny signature posing shoulders are formed at the juncture in presence of tWo Witnesses. i v l of the body portion With the tube and head, ERNEST GERLACH- the interior diameter of the tube and body portion beingequei throughout their length, Witnesses: and the interior diameter of the head being CHARLES SEIFERD,

l greater than that of the body portion. HENRY G. LIND.
